There are no shortcuts. There are firms with liquid nitrogen processors who do not have the 300 Below Inc. CRYO-Barrel Stress Relief Process. Abrupt contact with the liquid nitrogen will create stresses - not cure them. The results can be adverse at best - even disastrous. 300 Below Inc., in Decatur, Illinois is the headquarters and parent company of CRYO-Barrel Stress Relief.  The process for treating weapons using cryogenics originated here, at our facilities, where most major commercial cryogenic developments have been pioneered.  We utilize a proprietary computer profile and control program for the treatment of firearm barrels.  It's perfected, it's the original, it's reliable, and IT WORKS!!

For forty years competitors have been seeking to copy our created markets.  We have even seen these curious folks post "caution" notices on their websites while copying many of our photos.  The first patent issued for processing firearms was created in house by our team.  We still lead the pack in terms of cutting edge research and development.  When you trust us to treat your firearms, we back our word with an unconditional money-back guarantee.  We can count on two hands the number of minor incidents we've had after processing well over 50,000 barrels, and each incident was promptly resolved by our team.  We average less than a single scratch every three years.  We invite you to see our state of the art 10,000 s.f. facility.

There's a reason the military, like many other professional shooting groups in the past, continues to trust us to get the job done.  You never regret investing a few dollars more in quality workmanship. We are extremely thorough.  We have refused to take shortcuts for forty years, and relentlessly strive to do it right.  The first time.    Every barrel is treated as if your life depended on it.  We know that in MANY cases, it actually does.
